java how to combine two hashmap without duplicate entries -


I am trying to combine two different hamsters but in those two maps, there are some duplicate entries, so I combine After thoese entries will be removed. For example:

Hashmap 1:
100 Hello = 101 Good

Hashmap 2:

100 Hello < / P>

100 Hello = 101 Good-- 102 Good

I have tried putall , but it seems that it does not remove duplicate entries Can I help it on a faster way?

I do not see a problem in your approach. 

  Hashmap

output 

  {102 = well, 101 = well, 100 = hello}

, If your Hashmap operation is correct.

I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
